EPSS: 50.3% probability of exploitation in the next 30 days

Published: 2012-05-11 · updated 2026-06-16
Weakness: CWE-20

Description

sapi/cgi/cgi_main.c in PHP before 5.3.13 and 5.4.x before 5.4.3, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote attackers to cause a denial of service (resource consumption) by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'T' case. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1823.

Affected products

PHP: through 5.3.12; 1.0, 2.0, 2.0b10, 3.0, 3.0.1, 3.0.2 (+112)
